“Blisters” in radiator

[ApePat]

Hi there. We moved to a new build a few months ago. I just noted some “blisters” on the radiator which was not there before - not sure the cause. We have not used anything to clean it apart from microfibre clothes for dust. Just wondering if anyone has any idea - I am just worried if it’s more than a cosmetic issue. Ta.

New build ... should be under guarantee ... get them back in to replace it.

We have already had 1 radiator replaced recently due to a different issue - I am not sure if they will find a reason to say no as it’s been close to a year since we got the keys. We would keen to know why in case they say no.

Possibly poor paint job from the factory but not really your issue. The builder should resolve it.

Can't help thinking that's been painted to cover up damage to paint. Maybe with spray can as I've had problems with radiator spray paint.
